you know whats funny? the book i have doesnt show that number (high performance ford interchange, published by the same people your book comes from)....... the software i have only lists that head for 351's....... and most importantly i have never EVER seen one (or heard of anyone else here yanking their heads and finding those numbers).

the core sections in the two large shops i worked in literally had thousands of head cores at each shop. we're talking shelves floor to ceiling filled with heads, heads, and more heads. pretty strange that out of the thousands of sets of heads we had, plus all the heads the came thru the door for valve jobs or motor rebuilding i have never seen one. it really makes me wonder if its just bad info floating around somewhere.

btw, heres an arial from google maps to show the size we're talking about of head cores

Hamutoff

its just bad info
........and more than one confilicting piece of bad info on the same model year range..... I am beginning to think that perhaps 1983 engines when going down the assembly line had what ever was laying around installed. Exactly what book are you talking about my77stang could you scan/photo an image so I can document this in my spreadsheets I am 'cobbling' together just for this purpose.

Hamutoff

could this get more confusing? Yes. It is listed that way in yet ANOTHER book

its available for FREE download - I think its like a $30 book if you buy it, but is it worth anything if it has errors like the other books mentioned....

Here is the area in question:

For those of you building late-model 5.0L and 5.8L engines, cylinder head choices tend to be different, especially if you’re interested in meeting emission standards. From 1982-84, Ford used a D9AE-6049-AA cylinder head casting atop the 5.0L High Output V-8. This is not a high-performance cylinder head although it was used on the 1982-84 5.0L High Output engines. It is, however, a workable cylinder head that will come alive with port work and larger 1.94/1.60" Chevrolet valves.

Small-block Ford heads lost yardage in the performance arena after 1978 with Ford’s increasing attention to emissions and driveability. Ports became smaller for improved low-end torque and cleaner emissions. Although this works well in traffic, it doesn’t do much for our engine in higher RPM ranges. Despite the D9AE casting shortcomings, you can still port these heads and make power. However, this is not maximizing what you can do with a stock cylinder head.
The biggest shortcoming with the D9AE casting is the exhaust port with Ford’s infamous Thermactor injection “hump� in the port. It becomes very restrictive. However, this hump can be ground out and all restriction taken away with some Saturday afternoon labor on a work bench. For 1985 only, Ford went to the E5AE head, which was little more than a modified D9AE casting designed for easy roller tappet removal with the head installed. It is identifiable by the reliefs notched in the head at the lifter valley. Otherwise, it is virtually identical to the D9AE casting.
Ford began making improvements to the 5.0L/5.8L head in 1986 with the “high-swirl/fast burn� E6AE and E6TE castings. This head saw widespread use from 1986-88 depending on vehicle application. A shrouded intake valve was trademark to the “high-swirl/fast burn� concept. Thing is, the E6AE/E6TE head didn’t do much for power.

The E5TE and E7TE heads introduced for 1987 are undoubtedly the best late-model castings because the “high-swirl/fast burn� chamber is eliminated. This is more a return to the 1985 High Output/Truck head with improved water jacket passages. For you the engine builder, this head is good for an easy bonus 25-30 horsepower.

im really beginning to think these publications fail, because the D8OE head was used on every damn 302 i ever saw until 1985 when they made the E5AE (same damn head) and the E5TE (same as the E7TE). also, I have NEVER seen a E6 head that wasn't an E6SE (never saw an AE or TE, so im pretty sure thats bullsh*t too)

heres the pages from that book i have, it kinda stops @ 78, i can take like 8 million screenshots from my prosis software but thats just a pain in the @ss.

I'd get a decent set of heads like afr or canfield aluminum ones

my77stang, I have that same book. I wouldn't take everything in the book as gospel but it is a pretty cool book none the less.

are you sure there 4v heads? if so ill buy them
